Auto switching to Bluetooth input. - MTCD Android Head Units Q&A

I have two cars, both have android head unit in them (android 9 and 10)
With both the head unit switches automatically from radio to the phone Bluetooth on incoming phone call. And switch back to the original source when the call ends.
But none of then will automatically switch from radio to Bluetooth on any other sound input from the phone.
I could not find an option to allow auto switching to Bluetooth input.
For example:
While in my car I usually connects the phone to the head unit using Bluetooth.
I then hear radio from the head unit and run Waze on my phone (I don’t run it in the head unit as I better see the phone without lowering my eyes from the road).
When Waze say something, I don’t hear it, as the sound go to the head unit and it will not switch from the radio.
Another situation is I would like the head unit to switch from radio to Bluetooth when I start a podcast on the phone.
Can this be done on android head unit?

Best car integration kit?

For years I've been handling all the music in my car via a first-gen iPod mini under the passenger seat connected to a Harman/Kardon Drive+Play. It's got its flaws, but it works great. I turn on the car and it picks right up where it left off. The control is mounted right where my hand expects it to be and the screen is easily visible. No fuss, no muss.
I'm wondering if I can accomplish something similar with my Nexus One. What I DON'T want to do is have some complex setup where every time I get in the car I have to connect three cables and put the phone in some gawdy clamp mount, then be awkwardly trying to use the touch screen while driving, then having to stop playback and disconnect everything when I get out of the car.
I'm looking for a solution that is either one cable or automatic bluetooth. Preferably there would be an external monitor screen. I'd like a manual control that I could mount by the arm rest or steering wheel and use without looking at it. At minimum, I could do music and calls. Navigation would be a plus.
Does anything like this currently exist?
Sounds like your after any number of car headunits that support AD2P (audio over bluetooth), bluetooth voice, and navigation. Alpine, Eclipse and Kenwood all make good units that should do what you want. You should be able to leave your phone in your pocket and just have it connect via bluetooth when your in range.
I've had minimal success with the various Pioneer headunits due to them not supporting AD2P without additional controllers = more money.
I hadn't thought of just replacing the head unit but I suppose I'm due. I browsed Crutchfield but there's no filter for A2DP capability. Anyone have any suggestions for a DIN head unit with integrated A2DP and a color LCD screen?
I'm currently using a jvc kd-r900. It comes with a little Bluetooth adapter that you can plug into the rear USB port. I have it setup to auto start car home when it connects to the bluetooth. Usually by the time I get in, start the car and put my seat belt on, my phone is connected and ready to play music/calls/GPS/etc. I can start music either from my phone or just pressing the play/pause button on the head unit. Works really great. I can switch songs pause/play and make calls directly frm the head unit without having to touch my phone. My wife had her phone in her purse in the back seat and was still able to play music without touching the phone
Overall pretty pleased with the unit and it works great with my n1.

Can you browse/navigate Artist, Album, Track, etc. from the head unit? If so, this is probably exactly what I'm after.
I can't browse using the headunit. It only allows my to play/pause and skip tracks.
Ah, okay. Thanks for the tip. This looks like a good unit.
Anyone else have experiences with A2DP headunits?
This might be dumb. But do all android phones have this a2dp feature? Isn't it just the same as a Bluetooth headset sort of, so they ALL must have it? If so I'm definitely getting a new stereo! I just want to make sure that after my nexus I can still use this feature!
A2DP is a software thing. So as long as the phone has a Bluetooth 2.0 chip (the G1 does) and the operating system supports A2DP (At minimum, Froyo does) then you're good to go.
I use a THB BURY CC9060 Music. Full Bluetooth kit with full music control from a remote dash mounted screen and call handling.

Bluetooth Buggy

OK, so I am curious as to whether or not anyone else is having issues with the A2DP performance on this guy. When it works its great, sounds pretty good for BT. But here are two issues I have found.
When playing music over bluetooth, get/make a call it switches to handsfree fine, but when is switches back it the music clips on and off.
2nd. It seems to only pair with one A2DP device. I have a blackberry bluetooth gateway which works great. But when I pair it to my pioneer head unit, it only connects to the hands free profile, not A2DP. My deck works fine on all my other devices. I have to delete both pairings, reboot, and re-pair.
Idk but are they Bluetooth 4.0 compatible?
Hey,
So I do not have my HOX yet but your problem reminds me of another issue with bluetooth on some other phones.
Try this when you set up your pairings make sure you pair it FIRST whit the device you want to do A2DP streaming on (probably your head unit) then set it up with any other devices. Some times some phones or bluetooth head units will only connect A2DP with the first devices that it is paired with (what is some times considered the primary device).
Also when it cuts out on your rather than messing with your phone shut off your head unit or BT mount for like 15 seconds and turn it back on. Also toggle it off on your phone then toggle it on after the units are powered up. I had that bug with music after a call happen a lot in the past but it turned out it was my BT unit on my visor (it needed a firmware update) but still shutting it off would usually fix it.
EDIT
Also see if you can update the firmware on your BT units. If the phone is using 4.0 and they are using 3.0 there could be some comparability issues.
I have issues with my bluetooth also. Sometimes it just won't connect to my car's bluetooth. Usually it seems like it happens when it connects then i turn off the car, then when i go back in the car(like running in to the store real quick then coming back out) and it wont' reconnect unless I restart the phone. Not sure what the problem is.

Enonon G2110 with android 4.2 double DIN car stereo

I have an Enonon G2110 with android 4.2. It has RK3066 1.6Ghz cortex A9 Dual core, DDR3 1GB. I am overall happy with the unit but I do have a couple questions for you all with this stereo.
1, The SWC controls randomly stop working and will stay not working until I reboot the unit. It is hooked up using the SWC1 wire through the SWC board on my steering wheel and hooked back to ground. It is the resistance type where every button has a different resistance. It programs correctly in the SWC program on the unit. I also have the canbus set to none in the "factory settings" area.
Any fix for this?
2, Bluetooth. When connected to my phone (LG G3) and making or receiving a phone call, the volume is super low through the unit. I have the unit hooked up using RCAs only through an amp in my car. The bluetooth connection for music works fine and is the correct volume. Is there anyway to turn up this volume on the unit? Or another program for bluetooth connection?
Also I can't get my PLX devices bluetooth KIWI to connect to this unit. I have the program TORQUE to obd2 monitoring. Not sure if its just an issue with the bluetooth program or something I am missing. The KIWI connects and works fine on my G3.
3, Screen flicker. My car has auto headlights. I have the headlight input wire hooked to the unit to change the brightness depending on day/night. When it switches modes from day to night the screen flickers for about 3 seconds. Is this normal? Any fix for this?
4, Google services stopped error. If i happen to kill the car and have to restart the engine, the unit says shutting down and the screen turns off for a moment and then back on. When it comes back on the error "google services has stopped" and I hit OK. Is there away around this? (besides not killing the car of course) It's not a big issue or anything but its something I have noticed.
I tired asking these questions on someones post but it got lost in the shuffle. Any help with this would be greatly appreciated!

Bluetooth help, need some technical assistance.

I've got a new Honor 8 with the latest updates and one glaring issue. The bluetooth audio skips with my Kenwood KDC-X701 head unit, sometimes a whole song plays, sometimes I get a lot of random skips and pauses in the music like it's dropping connection. The phone is within 2 feet of the head unit so distance isn't an issue. I tried it key on engine off with everything else in the car turned off to rule out interference from anything else in the car like headlights, tail lights, alternator noise, etc. I connected it via the 3.5mm jack and had smooth playback without skipping so it's not an audio source issue. And just to rule out a BT issue with the phone, I connected to and had smooth audio with a generic Chinese BT puck in my home. This same head unit has had no issues streaming BT audio from an iPod Touch 5th gen so it's not simply a head unit with bad bluetooth, it's some kind of issue between the Honor 8 and the head unit. What I want to know is how to determine what BT protocol is in use between the Honor 8 and the head unit and then determine what BT protocol the iPod Touch used and see if there's some way to manually set how the Honor 8 connects via BT to the head unit.
Or is there something more simple I'm missing here? Some kind of power saving I need to turn off, some menu option I'm missing, I hope so.
I'm going to make sure the head unit is on the latest firmware, I believe it is but I'll check and report back if there was an update and if it did anything for the issue.
Ok so during a 5 minute call through the head unit tonight there were not any BT issues, so this must be a music specific BT protocol issue, I'm slowly getting closer to the root of it.
Seems putting it in the dash pocket directly below the head unit works better which is unnecessarily close (less than 4 inches away) and many times closer than the iPod Touch ever needed to be. So there's still some kind of issue but seems like I might have a work around, it only skipped twice in a 30 minute drive which is the best it's been.
8 hour drive today with only 5-7 drops an hour. Seems worse when I'm around a lot of traffic, sometimes or that could just be coincidence.
Sometimes it's also partly dropping, music keeps playing but other Bluetooth features aren't working like Google voice commands or making/taking calls. Weird!

Samsung Galaxy active 2 takes Bluetooth calls over Android auto head unit

So as the title says.....
I have a OnePlus 7 pro paired to a Samsung Galaxy active 2 watch. I love both devices BUT many times when I'm driving and using my Android auto head unit and I make or receive calls it usually has 3 options phone, speaker phone, and Bluetooth. If I let it use Bluetooth, it will *usually* go to my watch and not my Bluetooth audio for Android auto
I just want to be clear, it's a pioneer 4200nex head unit, not the Android auto app
I am rooted and have made a profile that is if connected to my head unit Bluetooth then it should disconnect from the watch and kill the watch app (tried with and without the killing the app part) all to no avail
I'm so confused, other than literally turning off Bluetooth on my watch to drive, (which kills battery because then it goes to 4g) is there anything I can do to make the head unit Bluetooth default for calls when connected?
